WASH-TU B.

SPECIFICATION forming part of Letters Patent No. 404,984, dated June 11,1889.

Application filed February 21, 1889. Serial No. 300,641. (No model.)

To all whom it may concern:

Be it known that I, ALBERT G. ROBINSON, of the city of Brooklyn, in thecounty of Kings and State of New York, have invented a. new and usefulImprovement in WVash-Tubs, of which the following is a specification.

My improvement is designed for so-called wash-tubs, and particularly forthat class of stationary wash-tubs in which the tub portion is composedof composite material, such as concrete, cement, or artificial stone.

I will describe in detail a Wash-tub embodying my improvement, andafterward point out its novel features in a claim.

In the accompanying drawings, Figure 1 is a perspective view of awash-tub embodying my improvement. Fig. 2 is avertical section thereof,taken on the line a; to, Fig. 1. Fig. 3 is a view in perspective of asecuring device which I may employ.

Similar letters of reference designate corresponding parts in all thefigures.

A designates the tub proper. As shown, it is double. The tub is to beerected upon suitable supports in a kitchen or wash-house.

B designates a top frame for the tub. This frame will ordinarily becomposed of wood. It is secured upon the top of the tub A, and isprovided with suitable openings giving admission to the interior of thetub, which openings are normally covered, as shown, by covers O, securedby hinges to the rear portion of the top frame B.

Difficulty has been experienced in securing the wooden top frame to thetub A when the latter is composed of composite material. To accomplishthis I provide the front edge of the top frame B with a downwardly andangularly extending rib or flanged portion 1). The front face of tubs ofthe character to which my improvement applies has also a downwardly andinwardly angular extension.

The angularly-extendin g portion 1) on the top frame, when the latter isin position upon the tub, embraces the upper portion of the front face,and its angle of extension is substantially the same as that of thefront face. When the portion 6 is drawn back against the front face andheld in such position, the top frame cannot be lifted off from the tub.In order to maintain the top frame in such position, I employ securingdevices D, by which the rear side of the top frame is secured to thetub. In the example of myimprovement shown such securing devices aremade of T- shaped pieces of metal, the lower legs of which are providedwith inwardly-extending pins or projections d. The upper portions, or b,of the devices are provided with screw-holes, through which screws maybe passed in order to secure the securing devices to the top frame B.The pins or projections d extend into suitably-formed apertures in therear side of the tub A, as shown more clearly in Fig. 2.

By the means described the top frame is firmly secured upon the tub andcannot be removed therefrom unless the securing device be detached fromthe top frame B.

What I claim as my invention, and desire to secure by Letters Patent, is

The combination, with a wash-tub having an inclined orangularly-extending front face, of a detachable frame arranged upon thetop of said tub and provided upon its "front edge with a downwardly andangularly extending portion embracing the upper portion of the frontface of the tub and upon its rear side with downwardly-extendingprojections for engaging the tub, substantially as specified.
